問題があった。The conventional termite control method is to spray a chemical solution using a power sprayer, but when spraying, a floating mist of the chemical solution is generated, which poses health and safety problems if workers are exposed to it. .

用にあたっては前記のような薬液の浮遊ミストに対する
作業者の安全確保が必須の要件となる。In particular, recently the use of chlordane-based chemicals, which have traditionally been used as termite control chemicals, has been banned, so organophosphorus-based chemicals are being used as a substitute, but organophosphorus-based chemicals are acutely toxic. Because of its strong strength, when using it, it is essential to ensure the safety of workers from the above-mentioned floating mist of the chemical solution.

行われており、薬液が水分散型の場合は、これに水溶性
の増粘剤、例えばデンプン、ＣＭＣ，ＭＣ１ＰＶＡ等を
添加して薬液を増粘させることが行われている。One method of preventing the generation of floating mist from such chemical solutions is to thicken the chemical solution and increase the size of the particles ejected from the spray nozzle. In the case of a mold, a water-soluble thickener such as starch, CMC, MC1PVA, etc. is added to the mold to thicken the chemical solution.

粘剤を用いて増粘させる方法は次のような問題点を有し
ていた。However, the method of thickening a water-dispersed chemical solution using a water-soluble thickener as described above has the following problems.
（イ）多量の増粘剤を必要とする。(b) Requires a large amount of thickener.
（ロ）粉末状態の増粘剤を直接薬液中に添加すると凝集
が起り固形物ができ、均一な増粘液にならない。(b) If a powdered thickener is added directly to a drug solution, agglomeration occurs and solid matter is formed, making it impossible to obtain a uniform thickened solution.
（ハ）増粘剤を溶解し、増粘液とするのに時間を要する
。(c) It takes time to dissolve the thickener and form a thickened liquid.
（ニ）増粘剤にはカビの生育するものもあり、薬液散布
後施工部分全体にカビが発生する場合も考えられる。(d) Some thickeners can grow mold, and it is possible that mold will grow on the entire construction area after spraying the chemical solution.

ような利点すなわち（Ａ）高吸水性樹脂の含有量が少量でも増粘効果がでる
。The present inventor uses a water-dispersible chemical solution as described above to prevent the generation of floating mist of the chemical solution when spraying the chemical solution, and ensures worker safety even when an organic phosphorus-based chemical is used as a termite control agent. As a result of extensive research on possible termite control construction methods, we found that a method of spraying a water-dispersible termite control solution containing a termite control agent and a super absorbent resin not only suppresses the generation of floating mist of the chemical solution during spraying, but also The following advantages are provided: (A) Even if the content of the superabsorbent resin is small, a thickening effect can be obtained.
（Ｂ）シロアリ防除薬剤と高吸水性樹脂を混合して短時

（Ｅ）現場でシロアリ防除薬剤と高吸水性樹脂を手軽に
混合でき作業性がよい。(E) Workability is good as termite control chemicals and super absorbent resin can be easily mixed on site.
